John Gill

Ye that stand in the house of the Lord,.... That have a place and standing there, and go not out, being sons as well as servants; See Gill on Psa 134:1 and See Gill on Psa 84:4; in the courts of the house of our God; alluding to the courts in the temple, the court of the priests, where they stood and ministered, slaying and offering their sacrifices; and the great court, where all the Israelites stood and worshipped, Ch2 4:9. So this may describe the worshippers of God in common, who should praise him: and happy are they that have a place here; see Psa 84:1.
